Carl Sagan's immortal words about how the universe is all there is and all there ever will be I wrote him off as an arrogant imbecile.
If that was your take-away from his message then perhaps you are the arrogant imbecile. He is reminding us about perspective and that by reevaluating our imagined significance that we might learn something about humility and simply live in awe about the majesty of the universe. You could just as easily attribute it to the majesty of God, Faith, if that suits your fancy. I have watched this video many times over the years and still to this day get emotional over it almost every time I watch it. The point is that all of our enmity and strife is so often self-induced... and perhaps if we were able to see our place in this world from a more humbled perspective that we might have a more harmonious coexistence.
